云南省十七县(市)兽类吸虱昆虫区系调查

FAUNA INVESTIGATION OF SUCKING LOUSE ON MAMMALS FROM SEVENTEEN COUNTIES IN YUNNAN PROVINCE,CHINA

为了解云南省吸虱昆虫区系分布状况,选择云南省境内17县(市)进行哺乳动物(主要为小兽)体表吸虱调查。小兽诱捕、吸虱采集及分类鉴定按常规方法进行。捕获的哺乳动物共7305只(含3只大型哺乳动物)被鉴定为啮齿目、食虫目、攀目、食肉目、兔形目和偶蹄目6个目中的11科28属47种。从7305只宿主体表共采集吸虱34540只,鉴定为7科9属29种(含寄生在偶蹄目上的2科2属3种)。调查结果表明,吸虱种类明显少于所捕获的哺乳动物宿主种类,29种吸虱在不同的动物地理区域分布不均衡,横断山中部小区和南部小区的种类相对较丰富,广布吸虱种类为太平洋甲胁虱、棘多板虱和麝钩板虱。

To understand the fauna of sucking lice on mammals in Yunnan Province of China, seventeen counties （towns） in Yunnan Province were chosen as the investigation sites. The hosts were captured by traps. The sucking lice on the body surface of mammals were all collected and identified. Total 7 305 individuals of 47 species of mammals were captured and 34 540 individuals of sucking lice from the hosts were collected. The 7 305 mammals were identified as 47 species, 28 genera, 11 families in 6 orders： Rodentia, Insectivora, Seandentia, Canivora, Lagomorpha and Artiodactyla. The lice were identified as 29 species of 9 genera in 7 families, including 2 species of 2 genera in 2 families from cloven-hoof mammals （ Artiodactyla）. The findings suggest that the louse species are much less than the species of their mammal hosts and geographical distribution of sucking lice are disparity in different areas. The species of sucking lice is relatively abundant in middle subregion of Hengduan Mountains and southern subregion of Hengduan Mountains of Yunnan Province. The wide spread species of sucking lice are Hoplopleura pacifica, Polyplax spinulosa and Ancistroplax crocidurae.
